Calorific value of the Nichrome wire is less than if the person plus the AC voltage of the maximum value of 120V was applied a DC voltage of 100V is proportional to the square of the voltage applied.
When a DC voltage is less than 100 V in addition to in addition to the maximum value of the AC voltage is proportional to the voltage of 120 V because the heat quantity of the nichrome wire is added to the square. At
